Review of Radio Science


Book Description

A triennial summation of the state of the art in radio science This book is the fourth in the modern series of triennial reviews prepared by the International Union of Radio Science to further communication and understanding of the status and future of radio science, both for those working in the field, and for those who want to know what is of current importance in this area. The International Union of Radio Science, URSI (Union Radio-Scientifique Internationale), has divided the subject of "Radio Science" according to the ten topics of the Scientific Commissions that make up URSI. This volume consists of thirty-eight original, peer-reviewed papers. Each paper provides a critical, in-depth review of–and, in many cases, tutorial on–advances and research that have been of significant importance within the area of interest of the Commissions during the past three to four years. Among the topics covered are: Electromagnetic metrology Fields and waves Signals and systems Electronics and photonics Electromagnetic noise and interference Wave propagation and remote sensing Ionospheric radio and propagation Waves in plasmas Radio astronomy Electromagnetics in biology and medicine With an included CD-ROM of the full book text, allowing the user to do full-text searching of all the papers, the Review of Radio Science: 1999—2002 is a resource of vital importance to anyone working in, or with an interest in, radio science.




Near-surface Geophysics


Book Description

Part 1, "fundamentals", includes magnetic and electrical methods, subsurface geophysics, near-surface seismology, electromagnetic induction, and ground-penetrating radar. Part 2, "applications", includes determination of physical properties, multimethod surveys and integrated interpretations, and model-based survey planning, execution, and interpretation.










Ground Penetrating Radar Theory and Applications


Book Description

Ground-penetrating radar (GPR) is a rapidly developing field that has seen tremendous progress over the past 15 years. The development of GPR spans aspects of geophysical science, technology, and a wide range of scientific and engineering applications. It is the breadth of applications that has made GPR such a valuable tool in the geophysical consulting and geotechnical engineering industries, has lead to its rapid development, and inspired new areas of research in academia. The topic of GPR has gone from not even being mentioned in geophysical texts ten years ago to being the focus of hundreds of research papers and special issues of journals dedicated to the topic. The explosion of primary literature devoted to GPR technology, theory and applications, has lead to a strong demand for an up-to-date synthesis and overview of this rapidly developing field. Because there are specifics in the utilization of GPR for different applications, a review of the current state of development of the applications along with the fundamental theory is required. This book will provide sufficient detail to allow both practitioners and newcomers to the area of GPR to use it as a handbook and primary research reference.*Review of GPR theory and applications by leaders in the field*Up-to-date information and references*Effective handbook and primary research reference for both experienced practitioners and newcomers




Geophysical Methods for Cultural Heritage Management


Book Description

This book provides information and tools necessary to bridge and integrate the knowledge gaps related to the acquisition and processing of archaeological data, specifically in the field of preventive diagnostics, urban centers, archaeological parks and historical monuments, through activities that involve the application of non-invasive diagnostic detection systems, in the field of applied geophysics. The principal aim of this book is to define a tool for experts that work in the frame of Cultural Heritage and to identify a procedure of intervention transferable and usable in different geographical contexts and areas of investigations: it could help to decide the better technique of investigation to apply in relation to the predictive characteristics of the archaeological site and the objectives of the survey. The book is divided in two parts. The first one explains the theory of ground high resolution penetrating radar (GPR), electrical resistivity tomography (ERT), controlled source electromagnetism system, differential magnetic method and the scenario of integrated methods of different geophysical techniques. Each section covers the basic theory (complete description of the physical parameters involved in the method), field instruments (description of all systems actually offered by commercial companies), field techniques (presentation of the main procedures and setting parameters used to explore the ground surface during data acquisition), techniques of data processing and representation (main processing routines and comparison between different techniques; presentation of different typologies of graphical representation), and the possibility and limitations of methods (explanation of best and worst conditions of implementation of the geophysical technique in relation to the contrasts between archaeological features and the natural background and the features of the instruments and arrays). The second part describes some applications of geophysical prospection to Cultural Heritage in detailed case histories, divided in sections relative to monuments, historical buildings, urban centres, archaeological parks and ancient viability. Moreover, examples of integration of three-dimensional reliefs and geophysical diagnostic of a monuments and studies of large scale reconnaissance implemented into a Geographical Information System are treated. In each case study the authors cover the description of the archaeological or historical contest; an explanation of the problem to solve; a choice of the geophysical methods; the setting of the procedure of data acquisition; techniques of data processing; a representation, interpretation, and discussion of the results.
